Django: limiting querysets in admin forms

Comments

Let’s suppose you have two related types of objects in your Django app. Call them Object and SuperObject, related ManyToMany‘ly. And when you add/change SuperObject in Django admin, there’s all Objects available for selection. But you need to limit the choices, and limit dynamically (perhaps, depending on current user). Here’s quite straightforward but working technique.

PostgreSQL on Gentoo: split ebuilds

Comments

Just a note for those who looks for info on Gentoo & PostgreSQL (like I did today):

  • yes, as you might be already suspecting, PostgreSQL has been split

  • [STRIKEOUT:yes, there’s a little howto] there was one. Just install dev-db/postgresql-base (if you don’t need server; also it’s a dep for lots of packages, for example, those with USE=”postgres”) or dev-db/postgresql-server (PostgreSQL server)

Got stable now, old-style packages are masked and will be removed.

High-level and low-level

Comments

Fresh impressions.

Low-level programming trap — writing for half of a day code instead of finding suitable ready-to-use module in five minutes.

High-level programming trap — looking for suitable module for a few hours instead of writing your own code in quarter of hour.

IMified

Now IMified works at last, so I can “spread the word” about it. But… it’s too late and I’m too lazy to type all that you can read on the off.site… (-;E

So go right there and find out how do you get notes, ToDos, reminders etc in your Jabber! (-:E

OpenSource warrior

I am great warrior of OpenSource, indeed. On Thu, Oct 18 Kubuntu and Xubuntu 7.10 were released and in that evening I’ve downloaded all eight .iso-images and put it out in local network for people who cannot download them by ourselves. And today I managed to re-upload two images to other server for Far East Ubuntu users (-%E
